Cold Air Intakes

You probably already know what the factory air intake on your Ford Ranger does. Also called an air induction system, it pulls air into your truck's engine cylinders through an intake manifold, where its oxygen content can mix with fuel. The pickup's spark plugs ignite the mix, it burns, and the motor you love off-roading with roars to life on its own power.

Want to improve both engine power output and efficiency? Replace that OEM air intake with a Roush Performance cold air intake. It'll enable your engine to get even cooler and denser (higher-quality) air for combustion, resulting in the exciting power bump you've been looking for.

How do cold air intakes differ from regular ones, and so, how do they work? It's simple. They relocate the engine air filter to a place where it can get direct access to freer-flowing, chillier air -- namely, near a fender or above a wheel well, and either way, just outside the engine compartment. Otherwise, your induction system -- namely, its air filter assembly, mass airflow and oxygen sensors, and air metering system -- works the same: it captures airborne contaminants, monitors and regulates air and exhaust levels, and feeds that info back to an engine control unit (ECU).

A Roush Ranger cold air intake, however, goes above and beyond OEM.

• For one, it dramatically increases airflow, and its sealing is CAD-designed, optimized to keep out heat.
• Secondly, its high-capacity air dry element filter is both washable and reusable, it doesn't require oiling, and its conical style offers 21 percent more surface area than a stock air filter. The result: enhanced engine performance -- namely, power gains of up to 8 pound-feet over factory torque rating.
• Best of all, it's durable, made up of injection-molded parts, not to mention that it maintains your factory airbox snorkel and provides aggressive induction noise that won't be confused for anything other than Roush.
